some basic information you should know before selecting a carbide-tipped tool

       

1.Carbide tipped tools are slightly more expensive, but they stay sharp anywhere from ten to twenty times longer than a simple steel tip.

2.Carbide tips are also less likely to crater when machining more abrasive materials.

3.Because of its strength, carbide sharpening requires a specific type of abrasive, preferably something coated in diamond or a carbide abrasive wheel.

4.Carbide is both highly heat resistant (melting point of 2,870 C / 5,200 F) and extremely hard (8.5-9.0 on the Mohs scale of mineral hardness.)

5.Carbide tipped tools have a longer "tool life" than basic steel tools because of their extreme durability. This is especially relevant for higher speeds and feeds associated with more aggressive machining. If you plan on using your tool frequently on hard or dense materials, carbide tips are a must.

6.C-2 carbide tips are used for cutting non-ferrous materials such as cast iron.

7.C-5 carbide tips are used for cutting steel materials.
